B66c 17/08; B60p 1/00, 1/02 ABSTRACT OF THE DISCLOSURE The cart construction forming the basis of the present invention is one that is to be employed in transporting waste material for feeding to a burner. The cart construction embodies a refuse receiving casing which is shiftable back and forth within wheeled frames. The cart further includes a pusher board construction which enables the refuse to be pushed forwardly from an open end of the casing into the :burner.

The present invention relates to burning apparatus, and more particularly, to means for transporting and discharging waste material to burning apparatus of the class known as incinerator apparatus of the type disclosed and claimed in my copending US. application Ser. No. 322,578, filed Nov. 7, 1963, now US. Patent No. 3,215,- 101, of which the instant application is a division thereof.

Fire burning apparatus of the type designated as incinerators have been employed for a great many years as a means for disposing of a great variety of trash, rubbish, waste material and the like. A problem with respect to the reuse of such incinerators relates to the transporting of the trash or other material to be burned and the feeding of such material to the burning apparatus. In the general practice heretofore employed, containers and similar transporting means carrying the trash are dumped or otherwise fed through the feed door of the incinerator. This method is objectionable in that it oftentimes results in the indiscriminate scattering of the waste material in the area of the incinerator, which is highly objectionable from a standpoint of appearance, cleanliness, and the like.

In the elimination of the foregoing and related disadvantages, it is therefore a principal object of the present invention to provide means for carrying waste material to :be burned in a new and novel manner.

Another object of the present invention is the provision of a cart for transporting and feeding waste material to a burner in a new and novel manner.

Still another object of the present invention is the provision of means for feeding waste material to a burning zone or like unit in an efiicient manner.

Other and additional objects of the present invention will become manifest from the ensuing description taken in conjunction with the accompanying drawings.

Broadly stated, the cart means of the present invention comprises a casing having a forward end and a rear end spaced from one another, said forward end being open and the rear end being apertured, pusher means movable back and forth within the casing, handle means secured at one end to said pusher board means with the opposite end of said handle means extending through the aperture in the rear end of said casing, wheeled frame means secured to the underside of said casing, pivotally connected vertical support means secured at its upper end to each side of said casing with the lower ends thereof connected to said frame means whereby the casing may be moved forwardly with respect to said wheel means, and spring means normally urging said casing rearwardly of said frame means.

To the accomplishment of the foregoing and related ends, the present invention then consists of the means hereinafter fully described and particularly pointed out in the claims, the annexed drawing and the following description setting forth in detail certain means in the carrying out of the invention, such disclosed means illustrating, however, but one of various ways in which the principle of the invention may be employed.

FIG. 1 is a side elevation of a waste material loading cart made in accordance with the present invention illustrating the position of the cart prior to the feeding to a furnace.

FIG. 2 is a side elevation of the loading cart shown in FIG. 1 illustrating the feeding of the waste material to a burning unit.

Referring now to FIGS. 1 and 2, the waste material cart, generally designated by reference numeral 75, is shown therein which is shown in use with burning apparatus of the type shown in my divisional copending application Ser. No. 322,578, filed Nov. 7, 1963, now U.S. Patent No. 3,215,101. The cart includes a rectangular casing 76 having its front end open and its rear end slotted to receive a long handle 77 therein. The handle 77 is connected at its forward end to a pusher board 78 of a'dimension corresponding to the interior dimensions of the casing 76.

The casing 76, as best shown in FIG. 2, is connected in pivotal relationship on each side at longitudinally spaced points to the upper end of horizontally spaced vertical bars 79 and 80. The opposite ends of the vertical bars 79 and 80 are, in turn, connected at longitudinally spaced points and in pivotal relationship to a pair of horizontal bars 81, thereby permitting the casing 76 to move back and forth. The laterally spaced horizontal bars 81 are connected at their respective front and rear ends to a pair of side frame members generally designated by reference numeral 82, and each of which includes a vertical forward element 83 and an inclined side element 84 extending upwardly and rearwardly from the lower end of the vertical forward element 83. The side element 84 is provided at its opposite end with a handle portion 85.

Each of the side elements 84 adjacent the handle portion is connected to the upper end of the vertical arm 86a of an L-shaped frame generally designated by reference numeral 86. The forward free end of the bottom horizontal arm 86b of the frame 86 is provided with a wheel 87 for easy movement of the cart assembly. A spring 88 is connected at one end to the bottom arm 86b of the frame 86 and at its other end to the vertical forward element 83. A latch 89 is provided on the handle portion to normally lock the casing 76 in place.

In operation, the cart 75 will be loaded with trash, with the pusher board 78 being in a retracted position. The loaded cart 75 is then pushed to the burner unit 10, as shown in FIG. 6. The latch 89 is released and the casing 76 tilts forward and upward on the pivoting of the vertical rods 79 and 80. The handle 77 then is pushed forward causing the pusher board 78 to force the waste material into the burning apparatus. After the casing 76 has been cleared of all waste material, the apertured end of the casing 76 is pulled backward and downwardly into the position that the casing 76 will normally rest in.

While the cart made in accordance with the present invention has been illustrated with a burner unit of the type shown in my copending divisional application Ser. No. 322,578, now US. Patent No. 3,215,101, it is to be clearly understood that the transporting and loading cart 75 may be employed with any burner or incinerator unit having a feed door either front loaded, side loaded, or rear loaded, so long as the forward end of the cart 75 may be placed in registry with the feed door of the furnace.

While there have been described herein what are at present considered preferred embodiments of the invention, it will be obvious to those skilled in the art that modifications and changes may be made therein without departing from the essence of the invention. It is therefore to be understood that the exemplary embodiments are illustrative and not restrictive of the invention, the scope of which is defined in the appended claims, and that all modifications that come within the meaning and range of equivalency of the claims are intended to be included therein.
